Abstract

In this paper, we present a compact PIFA antenna (11mmx13mmx5.6mm) operating at 900 MHz Australian ISM band, custom designed for implantation under the skin of a rat. The antenna bandwidth is enhanced by partially connecting the antenna ground plane with the RFID circuit ground plane, leaving an optimized slot between them. The antenna operating environment is modeled and included when the antenna is simulated and optimized. Our results show that directivity of the antenna also improves with the ground connection. The purpose of this research is to modify an RFID-based telemetry device, which operates well in free space, for implantation into the body of an experimental rat.
